Does that add too much weight to the structure. If you look at the picture these joists are all on steel hangars. It's a pavilion style.

Then I would stop it just short of the existing hanger and make sure there enough fasteners to transfer the load from the sister, through shear, back into the origina joist to be supported by the hanger
